Unfortunately, it is not a generic name. It has been a legal trademark of Colt since March 1967. Consumers may choose to claim they own an AR-15, but no manufacture who wants to stay out of court will ever use it. Even the company known as Armalite today (not the original Armalite) does not use the term "AR-15" to describe it's products.
